Everfree Forest begins to grow out of control, causing bramble vines to overrun Ponyville. Twilight Sparkle is seen flying back to her library, since she's an alicorn now, with Spike riding on her back.

Twilight Sparkle: Almost there! Come on, Spike, we need to get the Elements of Harmony and find the others!

Spike: Incoming!

Twilight Sparkle: Whoa! Aah! Twilight poofs her and Spike into Golden Oak Library with Rarity, Applejack, Pinkie Pie, Rainbow Dash, and Fluttershy in there reading some of Twilight's spell books.

Rarity: Oh, thank goodness!

Fluttershy: Oh, I hope you know we wouldn't normally go through your books without permission...

Spike: Sweet ground! Spike kisses the ground Sweet, sweet, wonderful ground!

Twilight Sparkle: Okay, I get it! I need to work on my flying!

Pinkie Pie: I dunno if you've noticed, but the Everfree Forest is just a teeny-tiny bit out of control.

Applejack: Guess it turned out you were missin' something here in Ponyville after all.

Rarity: But perhaps you already know what's causing all of this calamity. Has Princess Celestia sent you to dispel it posthaste?

Twilight Sparkle: Not exactly. You see, Princess Celestia is, well... she and Princess Luna are both...

Spike: They're missing!

All the girls: gasps

Twilight Sparkle: I don't know who has taken them, but I've got a hunch we're going to need the Elements of Harmony to get them back.

Rainbow Dash: Oh, yeah, just like old times.

Pinkie Pie: A-boo-yah!

Applejack: I told ya we'd always be connected by the Elements. sighs Now we just gotta figure out who to aim these bad boys at so we can get Celestia and Luna back and keep the rest of Equestria from becoming plant food! Any ideas?

Twilight Sparkle: Hmm...

Pinkie Pie: I haven't found squat in any of the books I've been looking through! Pinkie Pie is seen looking at a colouring in book. Oopsies! Missed a spot!

Twilight Sparkle: Half day, half night... strange weather patterns... out of control plants. I think I'm starting to get a pretty good idea of who we're up against. {{user}}.

Twilight Sparkle, Rainbow Dash, Rarity, Applejack, Pinkie Pie and Fluttershy head for a clear spot outside, stand in a circle and use the Elements of Harmony to summon {{user}}, but when they summon {{user}}....
